“Network automation with VR”, Karsten Nielsen, Unity Technologies
When you look at automation there is automation and/or automatic. Which would you have in your infrastructure also when it comes to your networking ? I would prefer to have automatic and the new VR in opennebula 5 helps us to get there.

“Hâpy, make OpenNebula easy for all!”, Philippe Caseiro, Cadoles
Hâpy is an EOLE Module who provides a very simple to setup OpenNebula ""Single node"" cluster. But you also can build a simple multi-node cluster with Hâpy little brothers (Hâpy Master and Hâpy Node). Created and used by the EOLE community of users this Linux distribution make testing and first usages of OpenNebula very easy.
 
“Evolution of OpenNebula at Netways”, Sebastian Saemann, Netways
We at Netways are using OpenNebula in production for more than 4 years now. I will show you and talk about the evolution of our cloud infrastructure from the early days to now with focus on the actual setup and its components, including Ceph, Puppet/Foreman and Fog.
 
“Provisioning Flexible and High Available Climate Data Services”, Marco Mancini, CMCC Foundation
The Euro-Mediterranean Center on Climate Change (CMCC) Foundation is a non-profit research institution that manages and promotes scientific and applied activities in the field of international climate change research.  In this talk, CLIMA, the climate information management platform that has been developed recently at CMCC Supercomputing Center, will be presented. The platform is based on iRODS, an open source data management software that provides features such as data discovery, automated data workflows, secure collaboration and data virtualization. The main goal in CLIMA is to provide climate data services such as data portals, data delivery, and data analytics, that are provisioned through OpenNebula private cloud by using features such as Oneflow and Onegate. Moreover, CLIMA can provision  high available climate data services, by using a cloud hybrid approach based on the federation of OpenNebula and iRODS zones defined on-premise and on Amazon AWS. 

"MICHAL - flexible infrastructure accounting framework", Michal Kimle, CESNET
This talk will introduce a flexible accounting framework with data visualization capabilities called MICHAL, that we at CESNET developed for our infrastructure. Framework is able to gather data from multiple sources, OpenNebula being one of them, process it and present the result in a form of charts. MICHAL isn't bind to only one platform and can be easily extended to support accounting of multiple parts of the infrastructure. As part of the presentation, we will discuss our data gathering techniques, MICHAL's design and functionality, currently available data processing modules for IaaS cloud and plans for the future development.

"The Lightway Approach to Build Cloud CyberSecurity Exercise Platform", Yi-Lun (Serena) Pan, National Center for High-performance Computing (NCHC)
In the era of Cloud Service and Internet of Things, information security has already become a transnational issue. In recent years, the large scale cyber attack via the connection of BotNet has become a thorny issue of Global information security. Taiwan is always the main target of international hackers due to the high dense of information devices and computers in campuses are always the favorite of hackers. To help tackling such an issue, the Ezilla, which is considered as a private Cloud toolkit ( integrated with OpenNebula), has been implemented by the CyberSecurity research team in the National Center for High-performance Computing (NCHC), Taiwan. Through the Ezilla which leverages OpenNebula and CyberSecuirty techniques, Cloud users can easily customize and configure a specified Cloud security training environment. It is an extremely lightweight approach helping users to access virtual computing resources. The main feature of this project is simplifying the utilization of Clouds. Our goal is to make Cloud security scientists or users painlessly to run their own CyberSecurity jobs on Cloud platforms, including Cyber Defense Exercise, Malware Knowledge Base, etc.. Based on the proposed CyberSecurity Exercise Platform, we also develop new functions which are  private Cloud information security training service, Captur the Flags (CTF) competition service, and virtual networking service for enterprise.

The current agenda is:

"Measuring and tuning VM performance", Boyan Krosnov, StorPool
In this session we'll explore measuring VM performance and evaluating changes to settings or infrastructure which can affect performance positively. We'll also share the best current practice for architecture for high performance clouds from our experience.

"OpenNebula, a story about flexibility and technological agnosticism", Alberto Picon Couselo, Todo En Cloud
Cloud providers are constantly addressing the technology limitations on their infrastructures, which must be overcome to meet customer needs. On this presentation, we will demonstrate how technological agnosticism and management flexibility of OpenNebula has allowed Todoencloud to provide the most efficient open source solution to the needs of its customers, choosing the most appropriate virtualization technology (Xen and KVM), storage approach (ZFS vs CEPH), Cloud Bursting solutions (Azure, Amazon) and customized networking topologies.

"The DRBD SDS for OpenNebula", Philipp Reisner,LINBIT
You will learn what DRBD is, where it came from in its 15 years of existence. How it evolved into a software defined storage solution interesting for users of OpenNebula and why it is very well suited for hyperconverged deployment architectures. The presentation will contain IO performance results and (if time permits) a live demo.

The current agenda is:

"A case study: how we move a traditional infrastructure to a service oriented one with OpenNebula", Alberto Zuin, Colossusbets LTD/Devuan Linux
In Colossusbets we moved a traditional infrastructure made with traditional paradigms to a service oriented one, with a mix of virtualisation technologies like KVM, Linux Containers and Docker. I'll explain the purpose behind the minimalist logic used by OpenNebula and Devuan Linux, the two component at the root of our new infrastructure.

"ONEDock: Docker as a hypervisor in ONE", Carlos de Alfonso, Universidad Politecnica de Valencia
Containers have recently grown in interest in the virtualization community because they are a lightweight alternative to full machine virtualization. Containers offer an operating system level virtualization, where the kernel controls the isolation of the different containers. That means less isolation than virtual machines, but also less overhead in the system because they share parts of the kernel. The most important developments in the Open Source community are LXC and Docker. ONEDock is a set of extensions for OpenNebula to use Docker as a hypervisor in ONE, to provide containers as if they were lightweight Virtual Machines (VM). The underlying idea is that when OpenNebula is asked for a VM, a Docker container will be deployed instead. In the context of OpenNebula, it is managed as if it was a VM, and the user will be able to use IP addresses to access to the container. In this session we will learn about the integration of Docker and ONE, wich kind of the available features in ONE have been incorporated to the Docker containers, and how the operations on VMs are translated to the containers in the context of ONE. Moreover we will discuss some technical details and technical decissions taken in ONEDock, and how the other operations (that have not been implemented yet) will be integrated in ONEDock.

"LAB ONE - how to actually get Vagrant running on OpenNebula?", Florian Heigl, Freelancer Consultant
Do you remember Vagrant? It was that last hipster thing before Docker turned into the most recent hipster thing! It's also still really helpful for software evaluations or lab environments. Normally, it works with VirtualBox on your laptop, but this approach can be too limiting. Even running just 10 VMs becomes a stretch on a laptop. It burns through your battery, SSD lifetime, disk space and threatens how many dozen browser tabs you can open... Enter the Vagrant OpenNebula providers! You can actually control Vagrant on your workstation but have the VMs running on your cloud. There are multiple ways to do that, and also limitations. In the workshop, we'll look at what is possible and how you can best benefit from - oh right! - your cloud!

"Icinga2 - APIFY them all", Achim Ledermüller, Netways GmbH
APIs build the basement for an easy integration of your tool stack. Fora simple and modern way to configure your monitoring system, Icinga2offers a secure REST interface to configure the objects and services tomonitor. After a short introduction to Icinga2 i will show a example howto combine OpenNebula and Icinga2 using VM hooks and the Icinga2 API.

"OpenNebula Sunstone integration with FreeIPA using Single Sign On", Alvaro Simon, UGent
FreeIPA is an integrated Identity and Authentication solution for Linux and Unix environments. It provides a centralized authentication and authorization information and it also stores user data information such as user names, groups, hosts and many different objects to manage the security aspects of a network of computers. FreeIPA uses different technologies, but the core of the authentication system is based on MIT Kerberos technology. Thanks to this technology the authentication works on the basis of tickets to allow users or nodes communicating over a non-secure network to prove their identity to get access to different services. In this talk we will show how it is possible to integrate Sunstone authentication with the FreeIPA SSO thanks to the new Sunstone remote authentication plugin provided by OpenNebula. We will describe how to setup Sunstone in an easy way to include Kerberos authentication using Apache and Phusion Passenger module. This configuration approach also changes the security mechanism used by libvirt to establish the connection between hypervisors. We will explain how it is possible, using the host keytabs generated by FreeIPA, to improve the security between the hypervisors when we have to migrate virtual machines in an insecure network.
